✦ Synopsis

Collisional energy transfer between '$ and 'Z: Rydberg s tates of K2 has been studied by optical-optical double resonance (OODR) resolved fluorescence spectroscopy. The collision-induced probability for transition from a '4 state to an adjacent 'Z: state of K2 depends much more strongly on AJ than on AE in each case studied. AJ=O collision transfer is more favorable than A.!= + 2, . . . for '4 odd Je levels. For '4 even Jf levels, A!= ? 1 transfers are most favorable. The measurements of intensities of '4, 'Xi +B 'l-I., u' ~2, J' = I4e transitions and fluorescence intensities show that the collision-induced transition probability of these 'k-'Zz systems is quite large

A theoretical analysis is given for the excitation transfer of Xe('P,) +N, (X IX ,') + Xe ( 'SO) + N, (B 'Qy). The analysis is based on (i} pure Coulomb interaction coupled with electron exchange and (ii) spin-dependent interaction between the collision partners. Both mechanisms can account for the
